Conference paper


A partial characterization of the observed isoenzymes of the glucose-6-phosphate dehydrogenase (G6PDH) in Cyanophora paradoxa is given. The enzyme activities of G6PDH and 6-phosphogluconate-dehydrogenase detected in both cytosolic and cyanoplast cell compartments in comparison with biochemical properties of the isoenzymes of the G6PDH and nutritional characteristics of the flagellate allow speculation about the role of the cytosolic pentose phosphate cycle in C. paradoxa.
